The first weekend closure of the Parkway East, which will allow crews to begin dismantling the soon-to-be-demolished Greenfield Bridge, is scheduled for the weekend before Thanksgiving Day.

The closure of Interstate 376 will start at 11 p.m. Nov. 20 and extend through 6 a.m. Nov. 23.

Another weekend closure is scheduled for 10 p.m. Dec. 4 through 5 p.m. Dec. 6.

Eastbound lanes, heading out of the city, will be closed from Exit 72A Oakland to Exit 74 Squirrel Hill/Homestead. Inbound lanes will be closed from Exit 78B Wilkinsburg/Forest Hills to Exit 74 Squirrel Hill/Homestead.

Posted detour routes for both inbound and outbound traffic will direct drivers off the parkway and through the city to re-enter the highway. Police will monitor traffic at intersections, but the city warns drivers to expect significant delays.

The main detour route for eastbound traffic has drivers exiting at Forbes Avenue, a left onto South Bellefield Avenue, a right onto Fifth Avenue and a right onto Penn Avenue to get back on the Parkway East via the on-ramp in Squirrel Hill. The reverse route is suggested for westbound drivers exiting at Wilkinsburg/Forest Hills.

PennDOT also suggests drivers take the Pennsylvania Turnpike in Monroeville to the Harmar interchange, and use southbound Route 28 to access Downtown. Drivers can also use the turnpike in Monroeville to access the Interstate 79 interchange in Cranberry, and take I-79 south to the Parkway North/Interstate 279 to Pittsburgh.

Shutting down the parkway is necessary to allow construction crews to begin removing concrete slabs from the Greenfield Bridge before its demolition in December.

The implosion, which will occur during the week between Christmas and New Year's Day, will require a five-day closure. The bridge is scheduled to be completed by May 2017.

A $12.34 million improvement project on Route 380 (Bigelow Boulevard, Baum Boulevard, North Craig Street and the Bloomfield Bridge) in the City of Pittsburgh, Allegheny County, will begin on Tuesday, June 30 weather permitting.

Roadway reconstruction work will occur on Route 380 (Baum Boulevard/North Craig Street/Bigelow Boulevard) between Morewood Avenue and Herron Avenue in the City of Pittsburgh.  The project includes full depth reconstruction from the Bigelow Boulevard eastbound off-ramp to the Bloomfield Bridge to the Baum Avenue Bridge over the PAT Busway.  Additionally, reconstruction of the Baum Avenue bridge deck and milling and resurfacing of Baum Avenue from the bridge to Morewood Avenue will occur.  Other work includes reconstruction of ADA curb cut ramps, traffic signal upgrades and pavement reconstruction at the Bloomfield Bridge.

Beginning at 2 a.m. on Tuesday, June 30 the ramp from eastbound (outbound) Bigelow Boulevard to the Bloomfield Bridge will close to traffic for 44 consecutive days for roadway reconstruction.  Traffic will be detoured.

Posted detour

  • Motorists will continue eastbound on Bigelow Boulevard past the ramp

  • Continue straight onto North Craig Street

  • Turn left onto Baum Boulevard

  • Follow Baum Boulevard to Liberty Avenue

  • Turn left onto Liberty Avenue and follow to the Bloomfield Bridge

  • End detour

Single-lane restrictions for structural steel work will begin at 6 a.m. on Tuesday, June 30 on the Baum Avenue Bridge over the PAT busway.  Long-term single-lane closures on the bridge will be implemented at a later date.

Roadway reconstruction work will begin tentatively on July 8 on Bigelow Boulevard between North Craig Street and approximately Herron Avenue.  All traffic will be shifted into the eastbound lanes.  A single lane will be maintained in each direction in the eastbound lanes as crews begin work in the westbound lanes.  Reconstruction work will continue through late August.  Once the work is complete, all traffic will be shifted into the newly constructed westbound lanes so the eastbound reconstruction can begin.

Additional work in 2015 that is currently unscheduled includes:

  • Roadway reconstruction of North Craig Street between Bigelow Boulevard and the Baum Avenue Bridge.  A 91 day closure will be required.

  • Multiple weekend closure of Blessing Street for roadway reconstruction.

  • Reconstruction work on the Bloomfield Bridge ramps at Bigelow Boulevard.  Two separate long-term ramp closures will occur.

The project will conclude in August of 2016.  Work occurring next year includes the deck replacement of the Baum Boulevard bridge and the milling and resurfacing of Baum Boulevard between the bridge and Morewood Avenue.
